Sentinel

take_while_view::sentinel::sentinel

take_while_view::sentinel::base

operator==(take_while_view::sentinel)

 

template<bool Const> class /*sentinel*/;		(since C++20)

The return type of take_while_view::end.

The type /*sentinel*/<true> is returned by the const-qualified overload. The type /*sentinel*/<false> is returned by the non-const-qualified overload.

The name of this class template (shown here as /*sentinel*/) is unspecified.

Typical implementation holds two data members: a sentinel that represents the end of the underlying view, and a pointer to the predicate.

Member types

Member type	Definition
Base(private)	const V if Const is true, otherwise V. The name is for exposition only

Member functions

(constructor)	constructs a sentinel (public member function)
base	returns the underlying sentinel (public member function)

Non-member functions

operator==

compares a sentinel with an iterator returned from take_while_view::begin (function)
